这篇文章主要介绍了如何使用rpm包方式安装Percona server，具有一定借鉴价值，感兴趣的朋友可以参考下，希望大家阅读完这篇文章之后大有收获，下面让小编带着大家一起了解一下。
Percona XtraDB是 InnoDB 存储引擎的增强版，被设计用来更好的使用更新计算机硬件系统的性能，同时还包含有一些在高性能环境下的新特性。XtraDB 存储引擎是完全的向下兼容，于是完全可以使用XtraDB来替代InnoDB存储引擎。
Percona XtraDB 包含有所有 InnoDB's 健壮性，可依赖的 ACID 兼容设计和高级 MVCC 架构。XtraDB 在 InnoDB 的坚实基础上构建，使 XtraDB 具有更多的特性，更好调用，更多的参数指标和更多的扩展。
尤其是，XtraDB 被设计用来在多核心的条件下更有效的使用内存和更加方便，更加可用。也解除了InnoDB的很多限制；提供了比InnoDB更多的配置和性能监控参数。
Percona XtraDB engine包含在Percona Server and MariaDB中。
Installing Percona Server on Red Hat Enterprise Linux
Percona Server跟MySQL一样有多种安装方法：yum Repositories、rpm、Binary Tarball、Source Tarball、Git Source Tree等，可以根据实际环境选择，具体安装步骤请参考官方文档。下文主要以rpm包在RHEL 6上的安装为例说明主要步骤
Installing Percona Server using rpm packages
1下载软件包
wget https://www.percona.com/downloads/Percona-Server-5.6/Percona-Server-5.6.29-76.2/binary/redhat/6/x86_64/Percona-Server-5.6.29-76.2-rddf26fe-el6-x86_64-bundle.tar
2 解压tar包
]# tar -xvf Percona-Server-5.6.29-76.2-rddf26fe-el6-x86_64-bundle.tar
]# ls *.rpm
Percona-Server-56-debuginfo-5.6.29-rel76.2.el6.x86_64.rpm
Percona-Server-server-56-5.6.29-rel76.2.el6.x86_64.rpm
Percona-Server-tokudb-56-5.6.29-rel76.2.el6.x86_64.rpm
Percona-Server-client-56-5.6.29-rel76.2.el6.x86_64.rpm
Percona-Server-shared-56-5.6.29-rel76.2.el6.x86_64.rpm
Percona-Server-devel-56-5.6.29-rel76.2.el6.x86_64.rpm
Percona-Server-test-56-5.6.29-rel76.2.el6.x86_64.rpm
3 安装Percona Server
]#rpm -ivh Percona-Server-server-56-5.6.29-rel76.2.el6.x86_64.rpm \
Percona-Server-client-56-5.6.29-rel76.2.el6.x86_64.rpm \
Percona-Server-shared-56-5.6.29-rel76.2.el6.x86_64.rpm
#以上三个rpm包仅仅为了完成Percona server的安装
#若需要（包含debugging, testing,etc等）,则直接安装所有的rpm包即可
]#rpm -ivh *.rpm
附：RHEL6上安装报错：libcrypto.so.10和libssl.so.10
error: Failed dependencies:
libcrypto.so.10(libcrypto.so.10)(64bit) is needed by Percona-Server-client-56-5.6.29-rel76.2.el6.x86_64
libssl.so.10(libssl.so.10)(64bit) is needed by Percona-Server-client-56-5.6.29-rel76.2.el6.x86_64
libcrypto.so.10(libcrypto.so.10)(64bit) is needed by Percona-Server-shared-56-5.6.29-rel76.2.el6.x86_64
libssl.so.10(libssl.so.10)(64bit) is needed by Percona-Server-shared-56-5.6.29-rel76.2.el6.x86_64
#RedHat EL6自带openssl-1.0.0版本，对于Percona-Server应该安装openssl-1.0.1的版本，安装新版本后，问题解决
]# rpm -ivh openssl10-libs-1.0.1e-1.ius.el6.x86_64.rpm --force
warning: openssl10-libs-1.0.1e-1.ius.el6.x86_64.rpm: Header V4 DSA/SHA1 Signature, key ID 9cd4953f: NOKEY

4 配置文件
Percona Server默认的数据文件路径在/var/lib/mysql/下
#编辑配置文件/etc/my.cnf
]# cat /etc/my.cnf
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
log-error=/var/log/mysqld.log
innodb_buffer_pool_size = 128M
注：配置文件有很多选项，具体的根据实际需求配置，此处只是简单配置了下而已
5 运行Percona Server
1. Starting the service
]# /etc/init.d/mysql start
Starting MySQL (Percona Server).............[ OK ]
2. Confirming that service is running
]# /etc/init.d/mysql status
MySQL (Percona Server) running (3369)[ OK ]
3. Stopping the service
]# /etc/init.d/mysql stop
Shutting down MySQL (Percona Server)..[ OK ]
4. Restarting the service
]# /etc/init.d/mysql restart

1. Stop the Percona Server service
]# /etc/init.d/mysql stop
Shutting down MySQL (Percona Server)..[ OK ]
2. Remove the packages
]# rpm -qa|grep -i percona
Percona-Server-client-56-5.6.29-rel76.2.el6.x86_64
Percona-Server-server-56-5.6.29-rel76.2.el6.x86_64
Percona-Server-shared-56-5.6.29-rel76.2.el6.x86_64
]# rpm -e Percona-Server-client-56-5.6.29-rel76.2.el6.x86_64 \
Percona-Server-server-56-5.6.29-rel76.2.el6.x86_64 \
Percona-Server-shared-56-5.6.29-rel76.2.el6.x86_64
]# rpm -qa|grep -i percona
3. Remove the data and configuration files
]# rm -rf /var/lib/mysql/ /etc/my.cnf
注：这里将删除所有的数据文件（databases, tables, logs, etc.），可能你环境中的datafile的位置并不是默认的/var/lib/mysql，而是其他的目录，卸载的时候根据实际情况删除文件
